Diagnosis with GDS

In the body electrical system, failure can be quickly diagnosed by using the vehicle diagnostic system (GDS). The diagnostic system (GDS) provides the following information.
1. Self diagnosis: Checking failure and code number (DTC)
2. Current data: Checking the system input/output data state
3. Actuation test: Checking the system operation condition
4. Additional function: Controlling other features including system option setting and zero point adjustment
Select the "Car model" and the "Cluster Module (CLU)" to be checked in order to check the vehicle with the tester
Select the "Current Data" menu to search the current state of the input/output data.
